I am running Linux Mint Mate 17.2 with an update Ubuntu mainline kernel
downloaded from here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1.1-unstable/
When I disconnect a mounted ext4 USB stick without properly unmounting it
first, the kernel crashes and I need to reboot. Here the relevant logs, I can
reproduce this every time I try:
